417 # From John Mackin (March 6, 1991):
418 # We in Australia have _never_ referred to DST as `daylight' time.
419 # It is called `summer' time. Now by a happy coincidence, `summer'
420 # and `standard' happen to start with the same letter; hence, the
421 # abbreviation does _not_ change...
422 # The legislation does not actually define abbreviations, at least
423 # in this State, but the abbreviation is just commonly taken to be the
424 # initials of the phrase, and the legislation here uniformly uses
425 # the phrase `summer time' and does not use the phrase `daylight
427 # Announcers on the Commonwealth radio network, the ABC (for Australian
428 # Broadcasting Commission), use the phrases `Eastern Standard Time'
429 # or `Eastern Summer Time'. (Note, though, that as I say in the
430 # current australasia file, there is really no such thing.) Announcers
431 # on its overseas service, Radio Australia, use the same phrases
432 # prefixed by the word `Australian' when referring to local times;
433 # time announcements on that service, naturally enough, are made in UTC.
435 # From Arthur David Olson (March 8 1992):
436 # Given the above, what's chosen for year-round use is:
437 # CST for any place operating at a GMTOFF of 9:30
438 # WST for any place operating at a GMTOFF of 8:00
439 # EST for any place operating at a GMTOFF of 10:00
441 # From Paul Eggert (November 8, 1994):
442 # Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
443 # Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
444 # reports that NSW's fall 1995 change will occur at 2:00,
445 # but Robert Elz says it's been 3:00 in Victoria since 1970
446 # and perhaps the newspaper's `2:00' is referring to standard time.
447 # And Robert Uzgalis <buz@cs.aukuni.ac.nz> says that the New Zealand Daylight
448 # Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
449 # time on both the first Sunday in October and the third Sunday in March.
450 # For now we'll continue to assume 3:00 for changes since 1970.
